MANKATO, Minn. -- The climate is certainly right for Adam Thielen to make a push for one of the Vikings' final wide receiver spots: He's spending his first days in the NFL on the same practice fields he played the past four years in college.

The Detroit Lakes native played four years at Minnesota State Mankato, graduating as the school's second-all-time leading receiver and helping the Mavericks to the NCAA Division II semifinals last season. He signed with the Vikings as an undrafted free agent this spring, and in the early days of camp, he has attracted crowds after just about every practice.

He has caught the eye of Vikings coaches during practice, too. Thielen made a handful of impressive catches during organized team activities and minicamp, and added another leaping grab in the Vikings' first practice Friday. He could be a candidate to make the team out of camp -- especially if the Vikings carry six receivers -- or to land on the practice squad.

"We have seen some flashes from Adam," offensive coordinator Bill Musgrave said Saturday. "He makes some spectacular catches. He made one yesterday where he took it off the top shelf, really elevated and made a great catch. He has done that consistently. We have seen good things."
